Thanks to an umadoshi link spam, I’ve just learned about Andrius Burba, a very talented photographer.
He creates a five-foot-square portable studio (great lights, black cloth) that’s topped with a frequently-cleaned plate of glass.
Then he puts animals on the glass and photographs them from below. AMAZING RESULTS!
you can see two groups of cats, one group of dogs, one group of horses as well as two behind-the-scenes videos (one’s embedded below).
